Method and cost of rock excavation, Inlet Swamp Drainage District, Lee County, Illinois

The Inlet Swamp Drainage District, comprising 32000 acres of rich muck land, lies in Lee County Illinois, between the Chicago and Northwestern Railway, the Illinois Central Railway and the Chicago, Milwaukee and St. Paul Railway. The District is fifteen miles long and from one to five miles wide. The watershed has approximately five times the area of the swamp, and in early days, as much as one-half the thirty two thousand acres was under water for practically the entire year. It was not unusual in the Spring, for the swamp to be under from two to five feet of water. The point where Inlet Swamp ends and Green River begins, is known as the Inlet. This is a limestone ledge four miles wide and of unknown depth, which acts as a dam at the lower end of the swamp --Description and History of the District, page 2

The design of a water supply distributing system for the City of St. James, Missouri

The design of the distributing system, being governed by the fire requirements, it is proposed to provide three 250-gallon fire streams under a hydrant pressure of 70 pounds per square inch for the business section, from Scioto St. to Bowman St and from Seymour St. to Meramec St with a maximum length of hose of six hundred feet; and two fire streams of a minimum total capacity of 425 gallons, each under a hydrant pressure of 72 pounds per square inch for the outlying district; the water to enter the system under a pressure of 100 pounds per square inch... The population of St. James, Mo by the census of 1910, is 1100 but provision is made for a possible increase to 1500 with a rate of consumption of 100 gallons per capita per day. For small cities, where the fire demand is relatively large, the assumption is made that it will increase but little with the increase of population. In the design of this system it is intended to provide a supply adequate to meet the demands, of the territory covered, for a period of twenty years. The system can easily be extended to take in new territory without increasing the size of the mains here designed --The Design of the Distributing System, pages 1-2

Developing control and integration software for flexible manufacturing systems

The slow growth of computer-integrated manufacturing is attributed to the complexity of designing and implementing their control and integration software. This article expands on a methodology for designing and implementing this software that was introduced in [16]. The goal of this methodology is to build flexible and resuable control and integration software for computer-integrated manufacturing systems. It hinges upon the concepts of software/hardware components, their assemblages, a distributed common language environment, formal models, and generic controllers. Major sources of flexibility are obtained by decoupling process plan models from the model of the factory floor and by using a generic controller. Reusability is achieved by building selfcontained software/hardware components with general, possibly parametrized, interfaces. The interplay between simulated and actual hardware internals of software/hardware components is used as the basis of a testing strategy that performs off-line simulation followed by on-line testing.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/43095/1/10952_2005_Article_BF02265064.pd
